Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and receptor modulators. Its enantiomeric purity makes it valuable for creating biologically active compounds where stereochemistry influences efficacy and safety. Commonly employed in asymmetric synthesis to introduce chirality into drug candidates targeting neurological and psychiatric disorders. Also utilized in the preparation of fluorinated analogs to enhance metabolic stability and membrane permeability in medicinal chemistry.
